Polar Bears
What species is the focus of our presentation?
Polar bear
What human activity releases large amounts of greenhouse gases into the atmosphere?
Burning fossil fuels
What happens to ocean levels when glaciers and ice sheets melt?
Sea level rises
Name one renewable energy source discussed in our solution.
Solar power or wind power
What ecosystem do polar bears live in?
The Arctic ecosystem
What is the main food source for polar bears?
Seals
What do greenhouse gases do to Earth's atmosphere?
They trap heat
According to NASA, about how many inches has the global sea level risen since 1993?
About 3.6 inches
What type of habitat can absorb carbon dioxide and protect wildlife?
Wetlands
In our food chain, what animal comes directly before the polar bear?
Seal
What do polar bears use as a platform for hunting seals?
Sea ice
What environmental problem causes glaciers and ice sheets to melt?
Climate change
What technology do scientists use to monitor sea level rise around the world?

Seal
What type of predator is at the top of a food chain?
Apex predator
Name one fossil fuel commonly used for energy.
Coal, oil, or natural gas
Which region of the world is experiencing rapid ice loss?
The Arctic
Which organization monitors oceans, weather, and sea levels?
NOAA
What can happen to a food web when important species begin to disappear?
The food web becomes disrupted or unbalanced.
Why does sea ice loss make it harder for polar bears to survive?
It reduces their hunting habitat and makes finding food more difficult.
How does burning fossil fuels eventually affect polar bears?
It causes climate change, melts sea ice, and reduces polar bear habitat.
What could happen to biodiversity if sea level rise and climate change continue?
Species may lose habitats, and biodiversity may decrease.
How does renewable energy help reduce sea level rise?
It reduces greenhouse gas emissions and slows climate change.
Why are polar bears important to the Arctic ecosystem?
They help control seal populations and maintain ecosystem balance.
